Because its not for coating metal,more for something like a Pelican Case, and from what I can tell about this paint "WITHOUT" having it in hand
and only what Ive read online, it dries like a rubber shell, thin so they talk about multipal coats.
Notes Ive taken on the Subject from other websites:
EMI shielding
There are a variety of Conductive Paint products available for application, including: nickel, graphite, copper, silver, and silver-copper hybrids.
• Nickel and graphite conductive paints provide excellent ESD coating protection, as well as moderate EMI RFI shielding effectiveness.
• Copper paints are a popular choice providing midrange shielding and conductivity performance while being very cost effective.
• Silver and silver-copper hybrid conductive paint offers higher levels of shielding effectiveness.
Question from reader Augustino: August 11, 2010
Miles -
Question... I'm reading that one should have electronic equipment such as 2 way radios, AM - FM - SHORTWAVE radios, etc... stored in a faraday cage
or box to protect from EMP.
And sure you can use a microwave oven to stash radios in but most are rather small. So as I'm reading and researching I see something that really
floors me! They say the best faraday is a galvanized garbage can. Place doubled up contractor grade trash bags one inside the other, inside the trash
can. Place items you want protected into the trash bags that are inside the garbage can. Place the lid on tight and for added security attach a copper
wire to the galvanized can and then to a grounded rod! There you go a super sized faraday container.

Response.
Virtually any metal container can be used as a Faraday cage. Actually, galvanized garbage cans are an inefficient method because of two reasons:
wasted space and insulation. They are round and things put into them are rectangular or square, so a lot of "corner space" cannot be used.
Second, the garbage bags are not sufficient insulation. One little tear in the bag allowing one item to touch the side of the metal can could be
enough to electrocute everything inside. Cardboard is a much better insulator.
Garbage cans can be used, but old filing cabinets or freezers are better. Pieces of cardboard can be easily cut to line the inside for insulation.
The shape of the interior space provides more items to be stored per square foot of exterior space. The shelving allows items to be separated and
organized, used as needed, and then easily stored safely again. With a garbage can, half the items would be deeply buried. Retrieval of one item
could mean removing half the items, and use such as that could easily translate into a tear in a garbage can liner which would endanger all of the
stored items.

Im not preaching any gospal here, just showing things Ive found in my search for EMP protection and hope for further input for use all to reach the
goal of the OP.
I beleave in multi protections, so Faraday Cages, Grounding etc. is all good, its what you can afford in these troubled times.
